Meet the Team

Exceptional Results, Exceptional Service

Our team is here to consult on technical or commercial issues, to help develop RFP specifications, trouble-shoot, make the switch to solids, or anything else about water treatment.


Jim Heimert ::: Founder

AP Tech’s founder, Jim Heimert, started his career like many water treatment professionals, by selling liquids. A chemist by education and a consultant by nature, once Jim discovered solids, he recognized their incredible potential to radically change water treatment — an industry that hasn’t changed much since its inception — for the better.

“I always sell from a technical standpoint. I was sure that if we can put water treatment chemistry together with liquids, I knew that we could do it without water. Same chemistry, different form. No fillers, no water, only the chemistry you need.” Jim continued, “Our customers [water treatment providers] know what’s in it and how it works. Their customers just know that solids work.”

Jim founded AP Tech to produce a superior solid chemistry water treatment product. Two decades later, AP Tech is the leading global supplier of solid chemistry technology and equipment. AP Tech’s water treatment programs are safer for people, the planet, for businesses, and for profit. Across the globe, solids provide an effective alternative for treating water where shipping, storage, and handling constraints of hazardous liquid chemicals are prohibitive.

Although solids are still only a minor percent of the total water treatment market compared to liquids, there are so many benefits that more and more programs are making the switch every day. Jim continues to lead the industry change by investing in a robust water treatment innovation pipeline for solids and equipment. He innovates on-behalf-of and in-collaboration-with water treatment partners to identify solutions to the many water treatment challenges their customers face around the world.

Founded in 1999, AP Tech now serves over 200 water treatment partners who supply AP Tech’s solid chemistry technology and equipment to water treatment programs to over 10,000 customers in North America, Central America, South America, United Kingdom, Europe, Australia, New Zealand, Korea, Malaysia, and Thailand, and South Africa.

In 2019, AP Tech moved and expanded its global corporate headquarters, manufacturing, and research facilities to West Chester, Ohio, USA. In 2013, European headquarters were opened. A warehouse is located in Middlesex (London) to serve the UK, European, and African markets. In addition to facilities in Ohio and the UK, AP Tech products are licensed for manufacturing in the Czech Republic, to further serve the UK and European markets, and Brazil.

AP Tech ranked in the Inc. 500/5000 list of the fastest growing privately held companies for five consecutive years and was nominated for the EPA Presidential Green Chemistry Award in 2007 and 2010. AP Tech has been a finalist in the Cincinnati Business Courier Green Awards and several chamber of commerce business award competitions.

David Naylor - AP Tech

David Naylor ::: Engineering Manager

AP Tech’s David Naylor manages the equipment and tech sides of the solid chemistry water treatment business.  

David and his team focus on advancing equipment design and performance. He manages a complete line of dissolving equipment that effectively and reliably delivers dissolved chemical solutions when used with AP Tech’s solids in a variety of water treatment applications. He helps customers develop their equipment plan for large-scale or remote boiler and cooling programs with multiple units and smaller water treatment systems.  
“Equipment. Programming. IT. I’m your guy,” David explains. “I’m proud to have helped design and program AP Tech’s enduroTEQ Ultra-S dissolver. It is the most revolutionary dissolver ever made — smart, small and simple —the Ultra-S is highly regarded in the water treatment industry for its innovative characteristics and small footprint.”
The team can help water treatment partners determine which equipment their customers need based on their water treatment environment and other aspects of a program. This may include analyzing wall space for mounting the equipment, understanding the reservoir need or if the system is gravity fed, if the water treater needs to feed DuroBrom, and how many units a customer may need.
“David leads equipment innovation efforts to help solve customer specific business needs or water treatment challenges,” said Matt Horine, AP Tech Managing Director. “This includes optimizing the sleek and neat appearance of wall or rack mounted equipment, scaling equipment to manage small or large water treatment programs, and process improvement.”

Andy Kinnett - AP Tech

Andy Kinnett ::: Product Manager


AP Tech’s Andy Kinnett manages the Research & Development Lab and the Quality Control Lab for the global manufacturer. In the R&D lab, Andy focuses on product improvements and manufacturing process improvements. In the quality lab, Andy oversees the testing of every batch of solid chemistry product for composition and conformance to assure customers are getting the same high-quality water treatment product every time.

“We’re constantly working to try and solve someone’s challenge. I enjoy the collaborative atmosphere. I love the problem-solving aspect of it,” stated Kinnett. “Sometimes it is coming up with a totally new product when they need to fill a gap. Other times it is bundling several solid chemistry products together to provide customers with the exact mix they had in their liquid chemistry program.”

AP Tech invests short- and long-term research projects with their water treatment partners to innovate products and equipment in an effort to solve their customer’s challenges. Andy helps manage these new product and equipment requests from idea to implementation.

“Since we moved to our new location, we have doubled our lab space. This provides Andy and his team even more capacity to get into the applications side of things. It’s critical for us to continue learning with our partners about how our solid chemistry water treatment products are applied in the field,” said Matt Horine, AP Tech Managing Director.

R&D is a collaborative effort between AP Tech’s technical and manufacturing teams and water treatment providers. Kinnett’s team explores a lot of ideas. Ideas with merit are tested in small batches in the lab to determine if there is a performance or efficiency benefit. After initial formulation and testing, the team designs a manufacturing process and begins applications testing.

Andy studied Mathematics at the University of Cincinnati.
